Tad's Roasted Potatoes

January 8, 2010

Test Kitchen-Approved

Author Notes:

Last year, after having spent 5 years testing recipes (with Merrill!) for a cookbook, it was time to actually sit down and write the book. I did so in the evenings, which meant that my husband, Tad, took over cooking dinner. Tad is the type of cook who prefers to find a few recipes he likes and master them so he can get in and out of the kitchen and back to reading the paper as quickly as possible. His piece de resistance is roasted potatoes, which he makes in a cast iron pan with lightly smashed whole garlic cloves and whatever herbs are in the fridge. He blankets them with olive oil, scatters on coarse salt and coarsely ground black pepper and then sticks the pan in a hot oven. They're delicious every time. Once when preparing the potatoes, though, Tad used some white potatoes that had been in the fridge for, oh, a month, give or take a few months. When the potatoes came out of the oven, they were as brown as a chestnut, with a thick, glistening crust, and as sweet as candy—far outpacing any version he'd made before. The secret, we eventually learned, was the old potatoes. As potatoes age, their starch turns to sugar, making them denser, softer and easier to caramelize.

Serves: 4
Prep time: 10 min
Cook time: 40 min


  • 3/4 pound old white potatoes, scrubbed and cut into 3/4-inch cubes
  • 1 splash olive oil
  • 8 sprigs herbs (any combination of thyme, sage and rosemary)
  • 2 garlic cloves, skins left on and lightly smashed
  • 1 pinch coarse salt
  • 1 pinch freshly ground black pepper
In This Recipe


  1. Heat the oven to 375° F. Spread the potatoes in a 12-inch, well-seasoned cast iron pan—they should fit comfortably in one layer. Douse with olive oil, like you're marinating them. Add the herbs and garlic, and season generously with salt and pepper. Toss the potatoes a few times to mix in the herbs and seasoning.
  2. Roast in the oven, scraping up and turning the potatoes every 10 minutes or so, until the potatoes are well caramelized and tender, about 40 minutes.

These potatoes look so good! Thanks for sharing. I will try them in my potato and kale salad: http://www.bitememore.com/feedme/531/warm-potato-kale-salad-recipe

I'm forever letting my potatoes get too old and soft and sprouty, so I'm loving this! Might I dare say I'll buy a bag and let them get that way ON PURPOSE this time?<br /><br />What surprises me in this recipe is the (relatively) low temperature! I frequently see roast potato recipes hover at 425-450 (Kenji's, Deb Perelman's, etc.).

You can definitely roast at a higher temperature if you like -- Tad prefers to cook his potatoes longer at a lower temp so all sides of the cut potatoes have a chance to caramelize.

sounds delicious but one thing thru me off. You keep your potatoes in the fridge??? I always thought you shouldn't do this. I keep mine in a bin in the pantry. Does this only work with potatoes that are cold? Sorry for the silly question?

Not a silly question at all. I only keep the potatoes in the fridge because our apt is warm and if left out, the potatoes sprout really quickly. So if you keep yours in a bin in the pantry, that's great, and they will work!

I found puzzling the recipe in the cookbook calling for 3 pounds of potatoes that had been in the fridge for a month. Who, pray tell, has room for long term storage for so many potatoes? It seems a bit odd especially in a book about planning and shopping for the week ahead. Of course there is no harm in looking a month ahead (in fact a zealot for monthly planning in our midst converted me to this way of thinking last year) but I hate to think that I could not get the best result with a weekly menu that appeals to me, because my potatoes had not been sitting around long enough. My store cupboard is not particularly warm -- in fact, it's rather cool -- but on the rare occasion when I find a stray potato that's been hiding for a few weeks, it's almost always covered with sprouts. So to the ice box those three pounds would go. Quite puzzling indeed.

Hi Beryl, Perhaps the book had a typo? The recipe above says 3/4 of a pound. Hope that helps! :)

It is 3 pounds in the book and that's because it's for a week-long menu in which the potatoes show up a few times!

Actually after I strained the oil and used it for dipping bread (added shredded parm, salt and pepper and red pepper flakes) ?

Best potatoes I've ever had. Restaurant quality!!

Tad is sitting next to me -- and is very pleased to hear that people are still finding his recipe after all these years!

Just saw your husband's recipe and about to try it. Sounds amazing. I'll have to change a few things like minced garlic n the seasons aren't exact but still should taste great

Great -- good luck!

I posted a comment about my teenage son liking these potatoes a few years ago. He is now in college, and still loves them. Last night was his last night home before heading back to school and I asked him if he wanted anything special for dinner, He specifically requested Tad's potatoes with hamburgers. So thank you, Amanda (and Tad), for this wonderful recipe that is now a family favorite in our household.

I'm so happy to hear this -- and so is Tad, who never imagined he could create a recipe that would be enjoyed by others! Hope your son has a great year at school!

I love that you made a new discovery with the "old' potatoes - I feel like I always have an extra potato or 2 around when I buy too many for a recipe. I love that this is an easy way to use them up!

Tad still makes these once a week -- because we always have potatoes lying around, as well!

Tried this last night with pretty fresh CSA potatoes and it turned out amazing!

We had some organic potatoes which were I thought long gone, but I scrubbed them and followed this easy (I don't cook, I bake) recipe and they were delish. Even my husband loved them, and he is the cook in the family. I left them in a bit longer to make sure they were crunchy on the outside...simple and low cal. Glad I found it.

What if you don't have a cast iron pan? What else can you use to still achieve this result?<br />Thanks!

A heavy roasting pan or any heavy pan, really, should help.

I made these last night and my teenage son said. "These are solid potatoes, Mom."

I've made potatoes six ways from Sunday, but I've never prepared them exactly like this. They were delightful. My 2 year old declared "delicious" and "yummy" while eating them (there are no sweeter words to this mother's ears!). Paired them with grilled hanger steak marinated in salmoriglio (from the simple sicilian-style flank steak recipe I posted on this site) and a green salad. These potatoes are definitely going into the repertoire.

Thanks for giving them a try -- love hanger steak, too!

Our potatoes were definitely beyond their prime and you're right, there is something about the flavor and texture that surpasses the fresher spuds.

Thanks for letting me know -- it's fun getting comments long after I post a recipe. Keeps it alive!

This recipe is perfectly simple. My potatoes came out of the oven crunchy on the outside, but deliciously smooth on the inside. I loved the smashed garlic. It was a nice surprise to get a hunk of a roasted clove in between potato bites.

Just forwarded your note to Tad -- he'll be delighted!

Don't think I had old potatoes, but it was lovely just the same. The large pieces of roasted herbs were delightful. This version of roasted potatoes has entered the regular rotation.
